What Is This Tool?
This converter allows you to transform data transfer measurements from SCSI (Fast Ultra) units to SCSI (Sync) units. It assists in aligning data rates for devices that operate under different SCSI synchronous transfer modes, ensuring compatibility with various high-performance storage and peripheral systems.
How to Use This Tool?
-
Enter the value in SCSI (Fast Ultra) units that you want to convert.
-
Select the units to convert from and to, in this case from SCSI (Fast Ultra) to SCSI (Sync).
-
Click the convert button to see the equivalent value in SCSI (Sync) units.
-
Review the conversion results and use them for storage or device configuration needs.
Key Features
-
Converts SCSI (Fast Ultra) units to SCSI (Sync) units accurately based on established conversion rates.
-
Supports measurement of data transfer for enterprise-grade storage solutions.
-
Browser-based and simple to use without installation.
-
Provides clear conversion examples for better understanding.
Examples
-
2 SCSI (Fast Ultra) equals 8 SCSI (Sync)
-
0.5 SCSI (Fast Ultra) equals 2 SCSI (Sync)
Common Use Cases
-
Aligning data transfer rates for high-performance hard-disk arrays and RAID controllers in server environments.
-
Configuring backup systems using tape drives and robotic tape libraries.
-
Connecting legacy high-bandwidth peripherals such as optical jukeboxes and video capture devices.
-
Negotiating transfer speeds for legacy SCSI devices that use synchronous transfer modes.
Tips & Best Practices
-
Ensure your devices support synchronous transfer modes before converting units.
-
Use the converter to align with specific negotiation parameters like clock period and offset.
-
Verify transfer rates post-conversion to confirm deterministic timing and consistent throughput.
-
Utilize the tool within enterprise storage environments for accurate configuration.
Limitations
-
Conversion depends on negotiation parameters between initiator and target, which may vary in practice.
-
Some legacy devices may only support asynchronous transfers, limiting compatibility.
-
Does not directly convert to physical bandwidth or affect cable specifications.
-
Real-world throughput might differ due to clock period and offset settings.
Frequently Asked Questions
-
What does SCSI (Fast Ultra) mean?
-
SCSI (Fast Ultra) refers to parallel SCSI signalling modes combining Fast and Ultra extensions to increase data throughput and reduce latency while maintaining compatibility with the SCSI command set.
-
Why convert from SCSI (Fast Ultra) to SCSI (Sync)?
-
Converting helps align data transfer rates with devices requiring synchronous clocking, enabling deterministic timing and stable throughput.
-
Can this conversion be used for all SCSI devices?
-
No, compatibility depends on device support for synchronous modes, and some legacy devices may only operate asynchronously.
Key Terminology
-
SCSI (Fast Ultra)
-
Parallel SCSI signalling modes combining Fast and Ultra extensions to boost throughput and reduce latency while using the SCSI command set.
-
SCSI (Sync)
-
Synchronous transfer mode in the SCSI protocol where data transfers follow a negotiated clock between devices, enabling higher throughput and predictable timing.
-
Negotiated Parameters
-
Clock period and offset settings agreed upon by initiator and target that determine effective data transfer rates in synchronous SCSI modes.
